The electronic hygrotherm senses the ambient temperature and relative humidity in an enclosure with electric/elec-
tronic components and turns on a heater (or alternatively a fan) at either set point, helping prevent the formation of
condensation in the enclosure. Due to its wide voltage range the hygrotherm can be utilised anywhere in the world.
The external sensor can be positioned freely anywhere in the enclosure for precise measurements.
> Temperature and humidity adjustable
> Wide voltage range
> Operating temperature down to -40°C
> High switching capacity
> With external sensor
